论文摘要
GW170817事件开辟了一个新窗口，以测试对一般相对性的修改，目的是在额外的重力理论中丢弃或施加强大的约束。关于这些理论，Randall-Sundrum Brane-World理论 - 4+1个时空模型，其中其协变量的爱因斯坦田间方程与额外的额外尺寸带来的新额外术语组成 - 在多门徒天文学领域开始测试。在同一背景下，本文的目的是通过测量引力和电磁信号之间的时间延迟来施加新的收缩：GW170817和最近的S190425Z，而不是此修改模型的免费宇宙学参数。我们假设引力波沿着额外尺寸的快捷方式传播。此外，我们考虑了标准的$λ$ CDM型号，并执行了一项可能性分析，以便研究诸如$ H_0 $张力的效果，与此额外的理论相比，在该理论的低能量限制中，获得了$ 0.2 \％$的$ H_0 $值的$ H_0 $值。
The GW170817 event opened a new window to test modifications to General Relativity with the aim of discard or impose strong constraints in extra dimension theories of gravity. Concerning these theories, the Randall-Sundrum brane-world theory -- 4+1 spacetime model where its covariant Einstein field equations are composed with new extra terms that comes from extra dimensions -- is begin tested in the multi-messenger astronomy field. In the same context, the aim of this paper is to impose new constrictions through measurements of the time-delay between the gravitational and electromagnetic signals: GW170817 and the recent S190425z, over the free cosmological parameters of this modified model. We assume that Gravitational Waves travel along a shortcut on the extra dimension. In addition, we consider the standard $Λ$CDM model and perform a likelihood analysis in order to study effects like the $H_0$ tension in comparison to this extra-dimensional theory, obtaining a reduced $H_0$ value of the order of $0.2\%$ in the low energy limit of this theory.
